GAS-MIXING VALVE FOR, EXliPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented Dec. 3, 1912.

Application filed January 4, 1912. Serial No. 669,382.

To all 'LU/LOWL it may concern Be it known that I, AooLri-i Brenna, a

citizen of the United States of America, and

resident of Wheeling, county of Ohio, and

State of \Vest Virginia, have invented certain new and usefulImprovements in Gas Mixing Valves for Explosive-Engines, of

ers, and specifically to a combined gas mixing valve and gasolenecarbureter.

The primary object of the-invention is to provide an integral structurefor use in connection with internal combustion engines, which shall havethe dual functions of mixing natural or artificial gas as an explosive.proper explosive mixture from either an aeriform gas or a'liquid gas.

Another object is to provide a device of the character mentioned for useon automobiles or other wheeled vehicles wherein an in ternal combustionengine is employed as a source of motive power,whieh adapted to feed tothe engine, in properlymixed explosive charges, gas supplied from a gasstorage tank, or to feed properly carburcted charges from a gasoleneerotlier liquid fuel supply. I

\Vith these and other objects in view, the invention "resides in thefeatures of construeti .=n, arrangement of parts and combinations ofelementswhich will hereinafter be exel'nplified, reference being had tothe accompanying drawings, forming a part of this specificatiim, inwhich Figure 1 is atop plan view of the invention; Fig. 2 is a sideelevation of the same; Fig. 3 is a vertical section on the line 3-3,Fig. 1; Fig. 4 is a horizontal section on the line 4-4. Fig. 2; and Fig.5 is a similar section on the line 5 5, Fig. 2.

Referring to said drawings, in which like designating charactersdistinguish like parts throughout the several viewsl indicates a casingin which is provided a mixing chamber 2 to which the gas or gasolene,according as one or the other is employed as fuel, is admitted andprepared for furnishing explosive charges to an engine cylinder orcylinders. Said casing is of substantially upright cylindrical form andhas its upper end flanged, as,shown at 3, for attachment to the usualintake pipe or. manifold of an internal combustion engine. The lower endof said casing is open and has mounted therein a valve 4 whereby theadmission of air to the mixing chamber 2 for mixing with the. gasoleneis controlled. Located in theupper end of the mixing chamber is athrottle valve 5 adapted to be manually operatedfrom the car-operatorsposition in the usual manner, as by a series of suitably connectedlevers including a lever B mounted upon the projecting end of a rotaryspindle 7 upon which said throttle valve is carried. For limiting theextent of closing movement of said throttle valve an outwardlyprojecting lug 8 carried by the casing has a set-screw 9 projectedtherethrough, constituting an adjustable stop for the lever (3.

Partially encircling the casing l is a reservoir 10 to which gasolene issupplied through a pipe 11 from a suitable reservoir or source ofsupply. Gasolene fromthe reservoir it passes by gravity through apassage 12 in the casing wall and is admitted to the mixing chamber nearthe lower end of the latter through a port 13 controlled by anadjustable needle valve 14.

The valve 4t at the lower end of the mixing chamber is normallymaintained closed by a compression spring 15 mounted on a stem 10 towhich the valve is attached, sa d spring being interposed between afixed. pl rt or member, as 17, and a head 18 carried by the outer end ofsaid stem.

Carried by the casing l is a laterally directed arm through whichle-tuls a p-...ssage 15) opening into the mixing chamber at a pointbelow the position 'of the throttle valve 5, said mssage havingeomnulnication at its opposite end with a gas chamber 20 formed within acasin 21 integral with said arm 40, said gas ehan'iber being adapted forreceiving natural or artificial gas through a pipe 22 leading from asource of supply, admision of said gas being controlled by a suitablymounted valve 23.

'gage'ment with the inner face of the head Said valve is normallymaintained closed against the pressure of the gas admitted through saidpipe by a compression spring 24 which has one end seated against theface of the valve and whose tension is regulated by an adjusti'ng screw25 projected through a removable cap 26 fitted in the end of the casing21 in a position facing said valve.

Leading into the mixing chamber 2 at a point below the gas passage 19 isa large air inlet passage 27 controlled bya valve QSwhich is normallyheld open, as by a retractile coil spring 29 interposed between a fixedportion or member 30 and a head 31 carried on the outer end of the stem32 on which said valve 28 is carried. Suitable means are employedwhereby said valve 28 may be seated for closing off the air supplythrough said passage 27, as when the gas supply to the gas'chamber 20 isshut off and gasolene is being used, the air suppl 1 for the gasolenebeing admitted through the lower valve-closed end of the mixing chamber2. The means herein depicted for closing the air passage 27 is butone ofvarious means which might be employed, the same comprising a yoke 33disposed in straddling relation to the valve stem 32 and having aninclined face or edge in sliding onof said stem. Said yoke has a stemslidably mounted in a guide member and'is adapted to be shifted forwardand retracted by any appropriate means for actuating the valve 28' tomove respectively to closed and open positions.

In practice, ither gas or gasolenc may be directed through the device,the former beingthoroughly mixed with air for producing a properexplosive mixture, and the latter being vaporized and properly mixed forproducing such mixture without the employment of either a spray or afloat feed, as hereinbefore indicated.

When gas is employed for fuel, the gasolene supply to the auxiliaryreservoir 10 is cut off and the valve 28 controlling the admission ofair through the air passage 27 is opened to freely admit a current ofair theretln-ough, which current is induced by the suction. of the engi;e. The suction produced by the engine pistons and acting on the mixingCllflllllIJGl Qthrcugh the intake manifold is regulated bymanipulatioi'i of the-throttle valve and'this suction acts to elevatethevalve 253 for admitting gas -to the gas chamber, the extent ofopening of said valve, and, consequently, the relative size of theadmitted charge, being dc pendent upon the extent of opening of thethrottle valve, as also the amount of air drawn through the passage 27for mixing with the gas.

lVhen gasolene is the fuel employed, the

gas supply through the pipe 22 is shut oil. and the valve 28 controllingthe admission of air through the passage 27 is caused to seat forclosing said passage. The su'ction of the engine acting directly uponthe gasolene, as'the latter gravitates to the port 13, draws a supply ofgasolene into the mixing chamber, the volume of which is regulated bythe degree of suction which the throttle valve permits to be inducedwithin said chamber; and said suction acting upon the valve 4, elevatessaid valve with'each engine pulsation a distance commensurate with theamountv of suction acting Within said chamber. Thus, a relatively largesupply of air is admitted with the gasolene to the mixing chamberwhereby proper carlun'etion may be effected in. the passage of themixture through the mixing chamber.

A pet cock 36 is preferably provided in the casing 31 through which gascontained in the gas chamber 20 may be exhausted when such exhaust isdesirable. Also provided at a suitable point, as in the cap 96, is a pin37, normally held by a spring 38 in an elevated position, which isadapted to be depressed into bearing contact with the face of the valve23 whereby the latter may be held seated, as when gas is the fuel usedand it is desired to have the contained in the chamber 20 exhaustedprior to taking in a fresh charge.

A small tubular opening 39 preferably provided in the side of the casing1 allowing free communication between the mixing chamber and theatmosphere, said passage servii'ig as a relief passage tln-ough whichexhaust of any back-firingcharge in the device is pin-united.

Having thus described my invention, whatclaim as new, and desire tosecure by Letters Patent, is i 1,.
